1 General description

CLRC661, the high performance multiprotocol NFC frontend.

The CLRC661 multiprotocol NFC frontend IC supports the following operating modes

? Read/write mode supporting ISO/IEC 14443 type A and MIFARE Classic communication mode

? Read/write mode supporting ISO/IEC 15693

? Read/write mode supporting ICODE EPC UID/ EPC OTP

? Read/write mode supporting ISO/IEC 18000-3 mode 3/ EPC Class-1 HF

The CLRC661’s internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/

IEC 14443A and MIFARE Classic IC-based cards and transponders without additional active circuitry. The

digital module manages the complete ISO/IEC 14443A framing and error detection functionality (parity and

CRC).

The CLRC661 supports the communication of MIFARE Classic with 1K memory, MIFARE Classic with 4K

memory, MIFARE Ultralight, MIFARE Ultralight C, MIFARE Plus, and MIFARE DESFire products. The CLRC661

supports higher transfer speeds of the MIFARE family up to 848 kbit/s in both directions.

The CLRC661 supports the vicinity protocol according to ISO/IEC15693, EPC UID and ISO/IEC 18000-3 mode

3/ EPC Class-1 HF.

The following host interfaces are supported:

? Serial Peripheral Interface (SPI)

? Serial UART (similar to RS232 with voltage levels dependent on pin voltage supply)

? I2C-bus interface (two versions are implemented: I2C and I2CL)

The CLRC661 supports the connection of a secure access module (SAM). A dedicated separate I2C interface is implemented for a connection of the SAM. The SAM can be used for high secure key storage and acts as a very performant cryptocoprocessor. A dedicated SAM is available for connection to the CLRC661. In this document, the term ?MIFARE Classic card“ refers to a MIFARE Classic IC-based contactless card.
